Translation Traps (for Russian speakers)
- Avoid translating 'cress' as 'кресс' (garden cress, Lepidium sativum), which is a different, edible plant. The shared etymology can cause confusion.
- Do not interpret 'rock' as music genre. It's purely descriptive of habitat.
Common Mistakes
- Misspelling as 'rockcrest' or 'rockcress' (should be two words or hyphenated).
- Confusing it with the edible 'watercress' (Nasturtium officinale).
- Using it as a general term for any small plant on a rock.

Frequently Asked Questions

Most species of rock cress thrive in full sun, which mimics their native alpine and rocky habitats. They generally perform poorly in deep shade.
Both are called 'rock cress' and are in the Brassicaceae family. Arabis typically has more white or pale pink flowers, while Aubrieta (false rock cress) is known for its vibrant purple/pink/magenta flowers and is extremely popular in wall and rock gardens.
It is commonly found as two separate words ('rock cress') or hyphenated ('rock-cress'), especially in formal horticultural writing. The closed form 'rockcress' is less standard.
